To Ill 'whom 1j may concern.'

Be it known that I, CHARLES J.l Drrrnnnu- NER, a subject of the German Emperor, and va resident of Cornwall, in the county of Orange and State of New York, have inventeda new and Improved Incubator, of Vwhich the following is a` full,- clear, and exact. description. I

The-object -o'f the invention is to provide a new and improved incubator, which is simple and durable in construction, composed of comparatively few parts which can be readily assembled and disassembled, and arranged to insure a uniform heating-0f the cg s in the hatching compartment, to provi e a proper circulation of air, to meisten the air,-and to furnish a suitable running -spacelor nursery for the hatched chicks. In order tol accomplish the desired result 'use is made of a lower heating chamber provided on top with a connecting tluelead lng to an upper heating chamber, the said heatin chambers being spaced apart to form etween them a `hatching compartment having a tray support Aand a nursery, and a water receptacle surrounding the said flue Within the said hatching compartment. A practical embodiment of the invention vis represented in the accompanying drawingsforming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a vertical central section of the incubator; Fig. 2 is a sectional plan View of the same on the line 2 2 of Fig. l; Fig. 3 is a. plan view of part of the bot- ,tom cover of the casing; and Fig. 4 is a sectional plan view of the heat escape valve on the top of the upper heating chamber.

The casing or shell A of the incubator' is preferably set on a table, bench or other support B, and the said casing 1s preferably made circular and provided in its side wall with a glass door C and glass windows l) at the hatching compartment E, below which is arranged a heating chamber F and above which. is located a heating chamber G. The lower andupper heating chambers F and G are connected with each other by a connect-ing flue H ertending centrally from the top oi' the lower heating chamber F to the bottom of the upper heating chamber G so as to support the upper heating chamber G 'from the tower heat-ing chamber F, which latter is i'oriuof of a metallic top and au integral side with its lower end on the bottom A of the. casing A. The top G" ot the upper heating chauibcr G provided with an outu'ardluetcntling annular ilange G resting on the upper edge of the casing i thus closing the open top of the said casiing.

Vvith'in the hatching compartment lf] arranged an annular tray support I held on posts or pins I attached to or resting ortho Wooden bottom I2 resting on top ofthe lower heat-ing chamber F. The support I is adapted to support a series of egg trays J, containing the eggs to be hatched, and preferably provided withI outwardly and downwardly incined bottoms, as plainly indicated in Fig. 1. By the useofthe door C convenient access is had to the hatching compartment E so as to permit oi manil'iulat-iug; the in the trays J, and .to shift thc latter around, for filling or emptying thc same, as thc case may be. By arranging the supports l a distance above the bottom I2 a niusery is provided for the chicks hatched from the eggs in the trays J and jumping trom the trays onto the bottom I2.

The connecting iiuell is surrounded by a water receptacle K forming, preferably, part of the flue H and opening into tho hatching compartment E at the upper inner ends of the t-rr J'. so that the Water in -evaporating supplies the air in the compartment E with the necessary moist-ure. The water receptacle K is adapted -to be filled With Water from the outside. by Way ofa suitable tank L attached to the outside of the casing A, and connected by a pipe L with the receptacle K. The receptacle K can be drained by a suitable valved drain pipe K leading to the outside of the casing A, as shown in Fig. l. v i

lVithin the upper heating chamber G is arranged a dome N provided at its open base N with posts for supporting the dome from the bottom of the upper heating chamber (l and for spacing the base N from the said bottom to allow the heatto pass from under the dome into the upper heating chamber G. The top of the dome N is pro vided with an outlet Yflue N8 extending through an opening G3 in the top G of the upper heating chamber G, and the said opening G3 is somewhat. larger in diameter than the. outlet tine N3, vand the said opening` G3 is controlled by a valve G, preferably made in sections, pivoted at G5 to the top G of the upper heating chamber G, so

. operator to swing the cover that the operator can into closed, partly open or wholly open position to allow escape of the heat from the upper'heating chamber G by Way of the opening G3.

The upper end of the outlet flue N3 is adapted to be opened and closed by a cover hung on a lever O connected by a cord, link or other means O2 with a thermostat or other contrivance for opening and closing the cover O according to the heat within the hatching chamber E.

The lower and upper heating chambers F and Gr are adapted to be heated by electrical heaters P, P, of any approved construction, the upper heater P being perferahly arranged within the dome N. If desired, use may be made of a lamp instead of the electrical heaters P and P, the lamp resting on a shelf B of the support B, and having its chimney extending through an opening B2 in the support B and through an opening A2 in the bottom A of the casing A, the upper end of the chimney opening into the central or connecting flue H. The opening A2 in the bottom A of the casing A is closed by a cover It as long the electrical heaters P and P are used, but when it is desired to use the lamp for heating purposes then the cover R is swung open, and for this purpose the free end of the cover is connected with a suitable handle R extending to the outside of the casing A to permit the R into open or closed position, as will be readily understood by reference to Figs. 1 and 3.

It will lbe noticed that by the arrangementdescribed the hatching compartment E and nursery is located between the heat ing chambers F and G, to insure a uniform temperature in the said hatching compartment and nursery so that the eggs are properly hatched and the chicks are protected against cold, and sufficient light is furnished by way of the glass door C and windows D. lBy the use of the dome N the heat is confined in the heating chamber G on top of the hatching compartment E. The water receptacle K surrounds the connecting flue H so thatsthe water is in direct contact with the heated tlue and consequently the water readily vaporizes to supply the air lin the hatching compartment and nursery with the necessary moisture conducive to the hatching of the eggs and the welfare of the chicks. On opening the door R more or less fresh air can be readily admitted to the heating compartment F by way of the openings B2 and Af. A

It will be noticed that the several parts within the casing A can be readily assembled and disassembled as the main parts are practically but three number, that is, t ie lower heating chamber F, connecting tube swing the valve Gr4 .H and water receptacle K are rigidly cona l l l www;

the casing, or removed therefrom in, reyex'seror other purposes-r Thev order for cleaning pipes L and K vare made p sections to permit of assembling ,the sections or removing the same. '4

he egg ,trays can be re position, shifted of the door C.
